The correct answer is option B, that is, it presents the correct sequence of events in Earth’s history.

The geological time scale signifies towards a framework of chronological dating that relates geological strata with time. It is used by geologists, paleontologists, and other scientists of the Earth to illustrate the relations and timings of incidents that have taken place during Earth's history.

Answer:

Option (B)

Explanation:

<u>A geological time scale is the sequence of events that have taken place in the past since the formation of the earth</u>. These events have formed due to the various geological process that has undergone in the past and are grouped in different zones. These show how the landscape formed and when the organisms started to appear and how the evolutionary process has taken place.

These events are grouped into three eons namely,

1) Hadean

2) Archaean

3) Proterozoic

4) Phanerozoic- It is again divided into three parts. They are-

(a) Paleozoic

(b) Mesozoic

(c) Cenozoic

These geological time scales play an important role in understanding the existence of different phases on earth and also it helps in identifying which age a rock belongs. It is very frequently used by geologists to determine the past activities.

Thus, the correct answer is Option (B).

Artyom0805 [142]

Answer:

The right matching of the scenario in the question are as follows:

1. OBSERVATION: Josh noticed that Julie ordered extra hot peppers and added hot sauce to her food

2. QUESTION: Josh wondered how to cook spicy Mexican food.

3. HYPOTHESIS: Josh decided jalapenos would be a good ingredient to add spice to the recipe.

4. EXPERIMENT: After chopping the jalapenos, he slowly added some to the enchilada filling, tasting as he went until he thought it was spicy enough.

5. RESULTS: Julie thought the enchiladas were delicious and exactly the right level of spice.

6. CONCLUSION: Josh determined that since Julie liked the meal, adding jalapenos to the recipe was a good way to make it spicy.

Explanation:

Scientific method is an organized steps of procedures that scientists used to study and gather knowledge about different phenomenons. The systematic steps of scientific method start with observation, the observed phenomenon usually make a scientist to ask questions that he doesn't have an answer to. This will prompt him to formulate an hypothesis and set up an experiment to see if his hypothesis is true or not. The result he obtains from the experiment will determine the type of conclusion he will make about his earlier observation. By following these steps, scientists usually obtain useful information that bring progress and advancement to humanity.

Explain the role of a hypothesis in a scientific investigation.

k0ka [10]

Answer:

A hypothesis is a testable proposition

used to explain scientific phenomena. It

may be based on previous observations

(a sort of educated guess) or it may

simply be a hunch. Most scientific

hypotheses are combinations of

observation and intuition. The important

thing is that the hypothesis be testable.

If the hypothesis is disproved through

testing, then it is discarded and a new

hypothesis is proposed. If the hypothesis

stands up to rigorous testing, then our

faith in the hypothesis is increased.

This system of careful, rigorous, and

unbiased testing of a hypothesis is what

characterizes the scientific method.

Hope it helps!

BARSIC [14]

Answer: The infrared radiations can detect the coolest and dimmest space objects.

In general, the coolest and darkest regions of space emit radiations of longer wavelengths. The Infrared telescope is used to find the cool, dim stars by slicing the interstellar dust bands and also measure the temperature of the planet of the solar system. The coldest stars do not emit light so they can be seen with the infrared telescopes only. In the visible region, blue stars are hottest and red are the coolest. The wavelength is inversely proportional to the energy emitted so the hottest stars are in the region of low wavelength in visible region.
